Bus bar

[kktuo]

I'm worried for my installation, i want to do 14s 192p ( about 500Ah for 18650 2.6Ah), i am using only 4 bus bar 11 AWG, about 4mm2, can be enough?

How I can calculate it for do a good bus bar?

Thanks in advance

I would consider max 80A current out of that. That defined on what i run today. I have 6*2.5 and thats the same as you have there kind of.

For more current double them up.

Thanks, I want limit it to 160A max, then I need put 4 more, in total 8 * 4mm2, I got copper cable from ground wire 35mm, 7 cable in total

Atleast i would do that...

Will tell that 99A is max on above with up to 3% loss Based on 60VDC
